In today’s world, electricity is the “lifeblood” of both production and daily life. Having a reliable backup power source is no longer optional—it’s essential. For medium-sized businesses, hotels, farms, and workshops, the 50kW alternator is often the ideal choice. It delivers just the right amount of power, comes at a reasonable investment cost, and fits a wide range of applications.
But the question that most people ask is: “What can a 50kW alternator actually run?” This article gives you a clear picture, with real-world examples from restaurants, hotels, farms, workshops, and office buildings.

Overview of the 50kW Alternator
What is a 50kW alternator?
A 50kW alternator is the generator head (alternator unit) that produces electricity with a rated power output of 50 kilowatts—equivalent to about 62.5 kVA. When paired with a diesel or gasoline engine, it forms a complete generator set capable of providing stable backup power.
Common specifications
Rated power output: 50kW (62.5 kVA)
Voltage: 380–400V (three-phase) or 220V (single-phase, depending on the model)
Frequency: 50Hz (standard in Vietnam and most Asian countries)
Power factor (cosφ): 0.8
Load capacity: Supports continuous operation for both industrial and commercial equipment.
What Can a 50kW Alternator Power?
To understand this better, let’s break it down by application. A 50kW alternator can run multiple devices at once, provided the total load does not exceed its capacity.
In Restaurants and Hotels
Lighting systems throughout the entire building
Passenger elevators (1–2 small lifts)
Centralized air-conditioning or 10–15 wall-mounted AC units (1.5HP each)
Industrial kitchen appliances (electric stoves, ovens, exhaust fans)
Commercial washing machines and dryers
A 50–70 room hotel (3–4 star category) can easily stay operational with a 50kW alternator as backup.
In Farms and Agriculture
Water pumps (5–10 units, 5HP each)
Ventilation fans for livestock barns (20–30 medium-sized fans)
Incubators, lighting, and heating lamps
Cold storage for produce or meat (1–2 small cold rooms, 20–30m³ each)
With a 50kW alternator, farms can maintain operations even during extended blackouts.
In Small Manufacturing Workshops
CNC machines (2–3 units) or traditional lathes/milling machines
Food packaging lines
Industrial dust collectors and exhaust systems
Welding machines and 10–15HP air compressors
This makes the 50kW alternator a popular choice for woodworking shops, textile facilities, and mechanical workshops.
In Offices and Medium-Sized Buildings
Computers, servers, and CCTV systems (100–150 computers simultaneously)
Office air conditioning (10–12 units, 2HP each)
Freight elevators or small lifts
Emergency lighting and fire protection systems
An office tower of 8–10 floors with around 2000m² floor space can remain fully functional with a 50kW alternator.
Reference Table: What a 50kW Alternator Can Power
| Application | Supported Equipment |
|---|---|
| Restaurants/Hotels | 15 AC units (1.5HP), full lighting, 1–2 small elevators |
| Farms & Agriculture | 5–10 water pumps, 20–30 ventilation fans, 1 small cold room |
| Small Workshops | 2–3 CNC machines, 10HP air compressor, packaging line |
| Offices/Buildings | 100–150 computers, 12 AC units (2HP), CCTV, fire safety |
How to Calculate Power Load for a 50kW Alternator
Many business owners wonder: “Is 50kW enough for me?” The answer depends on proper load calculation:
List all essential devices that must run during a power outage.
Identify power rating (kW or HP) of each device.
Add up the total load.
Include a 20% safety margin to avoid overload.
Example:
10 AC units (1.5HP each) → ~11kW
50 LED lights (20W each) → ~1kW
2 small elevators → ~10kW
Industrial washing + kitchen equipment → ~20kW
Total = 42kW. A 50kW alternator still has extra capacity to handle this comfortably.

Advantages of a 50kW Alternator
Cost-effective investment: only one-third the cost of a 150kW generator.
Versatile applications: suitable for both commercial and industrial use.
Fuel-efficient: average consumption 10–12 liters of diesel per hour at 75% load.
Compact & easy to maintain: small footprint, easy to transport and service.
Real-World Case Studies
Poultry farm in Binh Duong: a 50kW alternator keeps ventilation fans and lighting running during peak summer outages, preventing the loss of thousands of chickens.
Hotel in Phan Thiet: the alternator powers both air-conditioning and elevators, ensuring guests remain comfortable and the hotel maintains its reputation.
Mechanical workshop in Hanoi: with grid instability, the 50kW alternator keeps CNC machines operational, securing production schedules.
Conclusion: Who Should Use a 50kW Alternator?
If you are:
An owner of a restaurant, hotel, or small resort
A farm operator in livestock or hydroponic farming
A small manufacturing workshop needing stable power
A medium-sized office building or district-level healthcare facility
Then the 50kW alternator is your ideal solution: sufficient power, affordable cost, and reliable long-term operation.
